An Overview of Food Allergies

Key Points

This overview aims to clarify food allergies, distinguishing them from other food sensitivities and detailing their manifestations and management.
Conducted a literature review using PubMed and Google Scholar.
Analyzed symptoms, diagnosis, and treatment options for food allergies.
Reviewed the pathophysiology of the immune response to allergens.
Food allergies involve IgE antibody production leading to the release of histamines and allergic symptoms.
Symptoms can include hives, gastrointestinal issues, and respiratory problems.
Mild symptoms may be treated with antihistamines, while severe cases may require corticosteroids or epinephrine.

Abstract

Abstract: The prevalence of food allergies has been rising globally, affecting both children and adults. Misunderstanding food allergies can lead to unnecessary dietary restrictions or, in some cases, life-threatening consequences. This overview aims to describe food allergies, distinguish it from other forms of food sensitivity, and discuss its symptoms, diagnosis, and treatment. The literature source consists of relevant journals and books from the search engines PubMed and Google Scholar. When an individual with a food allergies consumes a particular allergen, their immune system produces IgE antibodies against that allergen. Upon subsequent exposure, these antibodies trigger the release of histamines and other inflammatory mediators from mast cells and basophils, resulting in allergic symptoms. The classic symptoms of a food allergies can range from mild to severe and include skin reactions (hives, eczema, or itching), gastrointestinal symptoms (nausea, vomiting, diarrhea, or abdominal pain), respiratory issues (sneezing, runny nose, coughing, or difficulty breathing) or systemic reactions (naphylaxis). The combination of of medical history, physical examination, and diagnostic tests in some cases can provide enough diagnostic reliability to make the diagnosis of a food allergies. Oral antihistamines may relief for mild allergic symptoms, whereas systemic corticosteroids may be prescribed for severe acute reactions or persistent inflammatory symptoms. Patients with systemic reactions should receive intramuscular epinephrine (adrenaline) during anaphylaxis. Keywords: Food Allergies, Pathophysiology, Symptoms, Diagnosis, Treatment.
